Author Correction: Evaluation of three methods for biomass estimation in small invertebrates, using three large disparate parasite species as model o…

2018

Invertebrate biomass is considered one of the main factors driving processes in ecosystems. It can be measured directly, primarily by weighing individuals, but more often indirect estimators are used. We developed two indirect and non-destructive approaches to estimate biomass of small invertebrates in a simple manner. The first one was based on clay modelling and the second one was based on image analysis implemented with open-source software. Furthermore, we tested the accuracy of the widely used geometric approximation method (third method). We applied these three different methods to three morphologically disparate model species, an acanthocephalan worm, a crustacean and a flatworm. To …

Vertex corrections for positive-definite spectral functions of simple metals

2016

We present a systematic study of vertex corrections in the homogeneous electron gas at metallic densities. The vertex diagrams are built using a recently proposed positive-definite diagrammatic expansion for the spectral function. The vertex function not only provides corrections to the well known plasmon and particle-hole scatterings, but also gives rise to new physical processes such as generation of two plasmon excitations or the decay of the one-particle state into a two-particles-one-hole state. By an efficient Monte Carlo momentum integration we are able to show that the additional scattering channels are responsible for the bandwidth reduction observed in photoemission experiments on…

On the convergence of zero-point vibrational corrections to nuclear shieldings and shielding anisotropies towards the complete basis set limit in wat…

2016

The method and basis set dependence of zero-point vibrational corrections (ZPVCs) to nuclear magnetic resonance shielding constants and anisotropies has been investigated using water as a test system. A systematic comparison has been made using the Hartree–Fock, second-order Møller–Plesset perturbation theory (MP2), coupled cluster singles and doubles (CCSD), coupled cluster singles and doubles with perturbative triples corrections (CCSD(T)) and Kohn–Sham density functional theory with the B3LYP exchange-correlation functional methods in combination with the second-order vibrational perturbation theory (VPT2) approach for the vibrational corrections. As basis sets, the correlation consisten…

Paschalna chrystologia Wacława Hryniewicza

2016

Na tle zasadniczych nurtów współczesnej chrystologii i klasyfikacji sporządzonej przez kard. Waltera Kaspera przedstawiono kilka istotnych założeń i cech chrystologii Wacława Hryniewicza. Źródła artykułu ograniczono do jego paschalnej trylogii: Chrystus nasza Pascha (1982), Nasza Pascha w Chrystusie (1987), Pascha Chrystusa w dziejach człowieka i wszechświata (1991). Głęboko biblijne, teologiczno-historycznie i ekumenicznie rozważania starały się pokazać, że paschalna chrystologia Hryniewicza unika niebezpieczeństwa jednostronnych ujęć różnych kierunków chrystologii kerygmatyczno-dogmatycznej, jak i chrystologii ukierunkowanych wyłącznie na Jezusa historycznego. Paschalna chrystologia zdaje…
